BACKGROUND OF THE INVENTION

1. Technical Field

The invention relates to vacuum cleaning systems, and in particular to astorage system connected to a vacuum source for storing an extendablelength of hose in a retracted condition within a storage housing. Moreparticularly, the invention relates to a small, compact storage systemadapted to be mounted in a concealed area within a home, such as in akitchen cabinet, which contains a sufficient length of an expandablehose for ease of cleanup of the adjacent room.

2. Background Information

Central vacuum systems for home and commercial use have been used formany years, examples of which are shown in U.S. Pat. Nos. 2,943,698 and3,173,164. These systems usually are comprised of a main vacuum sourcewhich is usually mounted in the basement or other location in thestructure or closely adjacent thereto. The vacuum source is connected tovarious outlet locations in the structure by tubing which terminate invalves mounted in the wall into which one end of a length of cleaninghose is removably connected for cleaning an area adjacent the wallvalve. These wall or hose end valves usually include some type ofclosure lid, which seals the hose receiving opening in the valveenabling another of the valves to be operational within the structure.Many of these valves are provided with electrical contacts or switcheswhich energize the main vacuum source. The vacuum hose also may beprovided with a pair of electric conductors for actuating the centralvacuum source by a switch on the handle, such as shown in U.S. Pat. Nos.4,064,355, 4,133.972, 4,194,081 and 4,368,348.

When using the cleaning system, the homeowner will generally have asingle length of cleaning hose with various attachments which are storedin a closet or other location requiring the hose to be moved from roomto room to be connected to the appropriate wall valve for cleaning thearea adjacent the valve location. In many situations, this is lessconvenient than desired since the homeowner must continually go to aremote location to retrieve the cleaning attachments and hose for use ina particular room and then return the cleaning attachment, cleaning wandand hose to the closet for final storage. Also, these storage areasbecome cluttered and occupy needed space in other closets of the house.

Some central vacuum cleaning systems attempt to solve some of thesestorage problems by having the hose retractably inserted into the vacuumsupply duct when not in use such as shown in U.S. Pat. Nos. 2,953,806,3,593,363. 5,526,842 and 7,010,829. In another attempt to solve thisstorage problem in a central cleaning system, an in-wall storage cabinetwas developed and shown in U.S. Pat. No. 5,740,581. However, the storagearrangement of this latter system requires the use of a power-drivenmechanism for retracting the hose when not in use. Although this mayperform satisfactory for its intended purpose, it is a more costlyinstallation than may be desired by many homeowners and it requires thehose to be dedicated to a single vacuum source. This prevents the samevacuum source to be energized for supplying a vacuum to other wallvalves in the structure. Also, these units may tend to be weak becausetheir size is very limited, and in addition, their dirt capacity mayalso be limited.

Due to the need to retrieve the vacuum hose from a storage area andconnected to an in-wall vacuum supply valve, many homeowners will notuse the system for small cleanups, such as small quantities of dirt orother debris such as spillages in a kitchen or the like, and will use amanual broom. These types of cleanups usually are required in a kitchen,workroom or laundry area, but do not receive the homeowner's immediateattention due to the need of retrieving the relative long length of hosefrom the storage area and connecting it to a central vacuum system.Afterwhich the hose has to be disconnected from the wall valve andreturned to the storage area.

Thus, the need exists for an improved hose storage system contained in asmall, compact hose storage housing which can be located inside of alarger storage cabinet, such as a kitchen sink cabinet or adjacentcabinet, which facilitates the use of the vacuum cleaning equipment in arelatively simple and convenient manner, and most importantly enables asufficient length of cleaning hose to be easily removed from andreturned to the storage housing when not in use, and which can enableother vacuum outlets in the structure to be active, that is, have thevacuum source supplied to the storage housing of the present inventionand to other vacuum outlets from a single central vacuum supply source,by providing a closure for an open end of the cleaning hose when not isuse and stored in the housing.

BRIEF SUMMARY OF THE INVENTION

The present invention provides a vacuum hose storage system having acompact hose storage housing for storing the cleaning hose, wherein thehousing preferably is mounted in a larger storage area or cabinet whichis connected to a vacuum source tube, which tube can extend from a maincentral vacuum source or from a self-contained vacuum source locatedwithin or adjacent the hose storage housing.

Another feature of the invention is to provide such a hose storagesystem in which the hose is permanently connected to a vacuum sourcetube by providing a sealing device at an open end of the hose handlewhich enables a central vacuum source to be active and provide a sourceof vacuum at other wall valves throughout the structure, enablinganother hose to be used by the homeowner at one or more of these othervalves if desired.

Still another feature of the invention is to provide such a hose storagesystem in which the hose when not in use is inserted into a pivotallymounted cradle which automatically actuates a switch to turn off thevacuum source and which seals the end of the hose to enable a centralvacuum source to be active and provide a source of vacuum at other wallvalves throughout the structure.

A further feature of the present invention is to provide the hosestorage housing with a plurality of rollers attached in a spacedrelationship between the walls of the housing within the storagecompartment around which the hose is placed in a looped fashionpreventing it from becoming tangled within the housing, and whichenables the hose to be easily grasped and pulled from the housing byexpanding the hose from a retracted to an extended position.

Another aspect of the invention is to form the rollers with a concaveouter circumference to ensure that the hose during expansion andcontraction remains in proper alignment within the storage housingthereby reducing friction during expansion and contraction of the hose.

Still another aspect of the present invention is to provide a sealingdevice for an open end of the hose handle when the handle is mounted ina storage cradle, which sealing device can have various configurationsfor sealing the open end of the handle while the vacuum supply isenergized, and in which an ON/OFF switch can be mounted in the supportcradle to turn the vacuum power supply ON and OFF automatically uponplacing the handle in the cradle.

Another aspect is to provide the hose with an expansion ratio of 5 to 1thereby enabling a long useable length of hose to be obtained from arelatively short contracted length of hose easily stored in a smallstorage area.

A further feature is to provide a vacuum storage system in which one ormore drive belts may extend between the hose storage rollers to assistin the uniform expansion and contraction of the hose as it is pulledfrom or retracted back into the housing by synchronizing the rotationalmovement of the rollers.

Still another feature of the invention is to provide a small compactstorage housing preferably mounted within an outer cabinet which storesa maximum length of hose in a minimum amount of storage space within thehousing whereby the hose end is easily removed from a storage cradlewhich upon removal will automatically turn the vacuum source ON and whenreturned to cradle will automatically turn the vacuum source OFF, inwhich a maximum length of hose can be stored and removed from a minimumstorage area, and in which the vacuum source can be connected at variouslocations in the storage housing and connected to a remotely locatedcentral vacuum source or to a dedicated source of vacuum adjacent thehose storage housing.

Another aspect is to use a neutrally biased hose or an expansion biasedhose which relies upon the retraction force created by the vacuum toassist in retracting the hose back into the housing after useeliminating the use of a spring biased retraction type of hose.

Still another feature of the invention is to use a switched hose foractuating the vacuum source by providing an ON/OFF switch on the wand orhandle which is connected to the vacuum source motor via electricalconductors extending through the hose.

A further feature is to provide a type of ratchet mechanism on the hosestorage rollers which will lock the rollers in position upon pulling thehose from within the storage housing which relieves the biasedretraction force on the hose avoiding the user having to continuallyapply a force to the hose when in use to prevent it from being pulledback into the housing.

A still further feature is to provide a high voltage source (120V or240V) to a power driven brush-type of cleaning attachment mounted on theend of the hose and connected to the remote source of voltage byelectrical conductors extending through the hose to enhance the cleaningability of the vacuum cleaning system. Another aspect of the inventionis to provide a length of tubing fixedly mounted in the storage housingand extending in a serpentine fashion in which the length of expandablehose is located within the tubing and has an inner end which isslidably, sealingly engaged within the tubing to enable the length ofhose to be pulled from its stored position within the tubing, which incombination with the natural expansion of the hose provides aconsiderably greater length of available hose from within the storagecompartment.

Another feature of the invention is to provide a control knob located ona handle receiving cradle which receives the end of the hose, which whenoperated controls the size of an opening in the internal vacuum line toregulate the strength of vacuum applied to the cleaning end of the hose.

Still another aspect of the invention is to provide a stiff wirepivotally mounted on a front wall of the housing which has a curvedconfiguration which can be manually moved into and out of engagementwith a helical spring incorporated within the vacuum hose to provide aone-way latch preventing movement of the hose towards its retractedposition within the housing, while permitting free pulling of the hosefrom the housing toward a desired extended position.

A further feature of the present invention is to provide a plurality oftool holder brackets secured to the housing with attachment thumbscrews.

Another feature of the present invention is to provide side panels onthe housing which may contain decorations or printed indicia which areremovably secured within complementary-shaped recesses formed in sidewalls of the housing.

A further aspect of the present invention is to provide a U-shapedmounting bracket which is secured to the bottom wall of a storagecabinet or other mounting structure whereupon the housing can besnap-fitted therein to removably mount the housing on the storagebracket permitting easy removal for maintenance.

Still another feature of the present invention is to mold a plurality ofstub shafts on opposed side walls of the housing to form roller shaftson which are rotatably mounted hose guide rollers within the internalstorage compartment of the housing thereby reducing production costs byeliminating mounting separate shafts on the side walls for mounting therollers thereon.

A still further aspect of the present invention is to form at leastthree holes in the spaced side walls of the housing, which holes receivestandoff brackets formed on cardboard packing panels which space thehousing from an outer packing box, which panels are then slidablyreceived within the outer packing box to provide a gap or crush zonebetween the housing and the packing box preventing damage to the housingwhen shipped and stored.

Still another aspect of the invention is to provide various snap-fitgrooves in the housing side walls enabling the housing side walls to besnap-fitted into and removed from the other portion of the housingenabling the internal mechanism of the housing to be readily accessiblefor servicing and maintenance procedures.

DETAILED DESCRIPTION OF THE INVENTION

The improved hose storage system of the present invention is indicatedgenerally at 1, and includes a storage housing 2 which is shown in FIG.1 mounted within the interior 3 of a larger cabinet 5. Storage cabinet 5preferably is of the type found in most kitchens, laundry rooms or workrooms. Hose storage system 1 is shown removed from cabinet 5 in FIG. 2.Housing 2 preferably has a parallelepiped configuration with opposedside walls 7, opposed top and bottom walls 9 and opposed back wall 10and front wall 11 which form a hollow interior storage compartment 13(FIG. 3). In the preferred embodiment, housing 2 will have a lengthbetween back and front walls 10 and 11 of twenty and one half inches, aheight between top and bottom walls 9 of seventeen inches, and athickness between side walls 7 of three and one quarter inches,providing a compact structure easily accommodated within the interior ofvarious types of outer cabinets 5. One or more brackets 12 may be usedto secure housing 2 within outer cabinet 5 as shown in FIG. 1.

In accordance with one of the features of the invention, an extendablehose 15 is mounted in a looped fashion about a plurality of guiderollers 17 which are rotatably mounted within housing 2 on shafts 19,which preferably extend between and are mounted on spaced side walls 7.In the preferred embodiment shown in FIG. 3, four rollers 17 areprovided which form for five loops in hose 15. Hose 15 preferably is atype of expandable hose as shown in FIGS. 12 and 13 which includes aninternal helical spring 21 which is encased in the outer layer ofmaterial 22. Hose 15 is pulled outwardly from housing 2 through a frontwall opening 20 and extends from a collapsed position as shown in FIGS.6 and 8 to a stretched or expanded position of FIG. 3. This will tensionspring 21 which then biases the hose towards the collapsed or retractedposition of FIGS. 2 and 6 when the outward pulling force exerted thereonis released. The looped arrangement of hose 15 about rollers 17 as shownin FIGS. 3 and 6, enables a relatively large length of hose 15 to bestored within compartment 13 without becoming entangled while providinga sufficient length of hose when pulled therefrom as shown in FIG. 3 toperform cleanup throughout a room in which cabinet 5 is located. Thepreferred hose 15 will have an elongated factor of 5, that is, if thehose has a collapsed length of eight feet and it has an extended lengthof forty feet. If desired, hose 15 can be a neutrally biased hose or anexpansion biased hose, which types rely solely on the vacuum source toretract it back into the housing.

In the preferred embodiment, hose 15 in a collapsed position as shown inFIG. 6 will have a length of 8 feet, and when stretched out with a 5 to1 ratio will have a length of approximately 40 feet. When in this fullystretched out position, approximately 8 feet will remain in storagecompartment 13 about rollers 17 providing approximately 32 feet of hoseextending from housing 2 for use in cleaning up an area about outerstorage cabinet 5. However, these lengths can change without affectingthe concept of the invention.

A handle 23 is attached to the distal open end 25 of hose 15 by aconnector 27 (FIG. 3). Handle 23 is a rigid tubular member formed ofplastic or metal and will have an open end 29 through which dirt entersthe hose interior. If desired, a cleaning attachment such as a rotarypower driven brush 26 as shown in FIG. 17 could be attached to a wand 28which in turn is attached to the open end of handle 23. However, formany of the types of cleanups for which hose 15 is intended to be used,a separate attachment is generally not required.

A vacuum source such as a central vacuum cleaning unit 33, as shown inFIG. 7, generally is mounted in a basement, attic etc. of the building,can be connected directly to housing 2 by a length of tubing 35 or withan elbow pipe 38 as shown in FIG. 1. A vacuum source such as aself-contained vacuum producing motor 32, can be mounted within aseparate housing 31 (FIG. 15) that can be attached to a side wall 7 ofhousing 2 or mounted adjacent thereto and pneumatically connected tohose 15 by a section of tubing 30.

If desired, a special tube and hose connector 37 can be mounted in alower rear corner of housing 2 (FIG. 16) and may have a plurality ofoutlets, such as outlet 39 in rear wall 10, a bottom outlet 41 in bottomwall 9 and a pair of opposed side wall outlets 43 formed in side walls7. This provides other attachment locations for a section of tubingwhich is connected to the vacuum source depending upon the location ofhousing 2 within the larger outer storage cabinet 5, and the bestlocation for the incoming vacuum supply tube. Any non-used tubingoutlets as shown in FIG. 16 can easily be sealed by a cup-shaped seal 46when not in use.

In accordance with another feature of the invention, a hose receivingcradle 45 is located in front wall 11 of housing 2 and accessiblethrough an opening 44 formed in front wall 11 (FIGS. 1 and 2). Cradle 45includes a short section of tube 47 having a hollow interior 48 and ispivotally mounted by a pivot 50 between side walls 7 and is adapted toslidably receive handle 23 therein in a generally sliding frictional fitwhen the hose is not in use as shown in FIGS. 2 and 4. After insertionof the open end of handle 23 therein, the handle is pivoted downwardlyas shown by Arrow A (FIG. 4) into the final stored position of FIG. 5.The inner end of cradle 45 is formed with a projection 51 which engagesand actuates an ON/OFF switch 53 which is mounted closely adjacentthereto. This movement of cradle 45 from the ON position of FIG. 4 tothe OFF position of FIG. 5 will turn the switch off. Switch 53 isconnected to the vacuum power source by a plurality of electricalconductors 55. When handle 23 is in the storage position as shown inFIGS. 2 and 5, the switch is in the OFF position and when the userdesires to use the vacuum system for a quick cleanup job, the user willmerely grasp handle 23 and pivot it upwardly from the OFF position ofFIG. 5 to the ON position of FIG. 4. This movement will automaticallyturn the vacuum source on, afterwhich the user merely slides the handleoutwardly from the cradle as shown by Arrow B and then will pulloutwardly on the hose in the direction of Arrow C, FIG. 3. This willstart the hose to expand from its coiled condition to an expandedcondition, as well as unwrapping it from around rollers 17.

Upon completion of a cleaning operation, the user will merely relax thepulling force on the hose wherein the expanded internal helical spring21 of the hose will bias the hose toward a retracted coiled loopedposition around rollers 17 until the handle 23 is replaced into cradle45 in the position as shown in FIG. 4. The handle is then pivoteddownwardly to the full storage position of FIG. 5 which willautomatically shutoff the vacuum source by actuation of switch 53. Also,retraction of the hose back into the housing is assisted by the force ofthe vacuum exerted on the hose which also biases the hose towards aretracted position. However, neither of the biasing force exerted on thehose by helical spring 21 or the vacuum source, is sufficiently great torequire a large force to be exerted on the hose by the user to move itfrom the collapsed retracted position to its extended position and tomaintain it in the extended position during a cleaning operation.However, this biasing force does assist in retracting the hose into itscoiled looped position after cleanup has been accomplished. Also,storage system 1 can use a neutrally or expansion biased hose ifdesired, which relies solely on the vacuum source for retraction of thehose back into the housing.

FIG. 8 shows a slightly modified form of the present invention in whichone or more drive belts 62 and 63 may extend around adjacent pairs ofrollers 17 to assist in the extension and retraction of the hose fromand back into the housing. Upon initially pulling the hose from housing2 in the direction of Arrow D (FIG. 8), the hose will immediately startto move about and rotate the lowermost roller 17A as shown by Arrow E.The next roller 17B begins to rotate shortly thereafter as the hose isstretched and starts to move about roller 17B as shown by Arrow F. Thisprogresses to the next roller 17C and then to roller 170 in a slighttime delay progression. By the use of drive belts 62 and 63, the initialrotation of roller 17A will automatically start roller 17C rotatingalmost simultaneously with the rotation of roller 17A. Likewise roller17D will begin to rotate almost simultaneously upon the rotation ofroller 17B due to its connection therewith by drive belt 62. The use ofdrive belts 62 and 63 will assist in starting movement of all of thesections of hose and their corresponding rollers almost at the same timeto greatly facilitate the removal of the hose from within housing 2instead of the delayed sequence which occurs as the hose is pulled fromthe housing without connecting belts 62 and 63. Likewise, upon the hosebeginning to retract back into the housing without the use of the belts,roller 17A will begin to rotate followed shortly by the rotation of 17B,then roller 17C and finally roller 17D in a time delay sequence. The useof drive belts 62 and 63 will again enable the sections of hose andassociated rollers to move more in unison assisting the retraction ofthe hose back into housing 2.

In accordance with another feature of the invention, one or more ratchetmechanisms 65 can be mounted on one or more of the rollers which whenthe hose is pulled from within housing 2 will prevent the rollers fromhaving a tendency to rotate backwards since they are retained in theirforward rotated position by the ratchet mechanism. This assists inreducing the biasing retraction force exerted on the hose by internalhelical spring 21 and the internal vacuum. This reduces the fatigue onthe user by not requiring the user to continually exert an outward forceon the hose to prevent its retraction back into housing 2. The ratchetmechanism can be easily reduced by suddenly pulling out on the hose andthen releasing this pulling force permitting the one or more rollers onwhich the ratchet mechanism are connected to rotate freely in thereverse direction. This type of ratchet mechanisms is well-known in theart such as used for vehicle seat belts and similar applications, andthus the details thereof are not described in further detail.

A modified cradle 66 is shown in FIGS. 14 and 16 and includes a shutoffvalve indicated generally at 67. Shutoff valve 67 is mounted in acompartment 69 formed at the corner of front wall 11 and top wall 9 forstoring handle 23 in a readily accessible position. Shutoff valve 67includes a sealing plate 68 which is biased by a compression spring 70toward open end 29 of handle 23 for automatically sealing open end 29upon insertion of the handle end through a front wall opening 72.Sealing plate 68 preferably will be used when the vacuum producingsource is the central vacuum cleaning unit 33 as shown in FIG. 7, whichis connected to other outlets throughout the building. This enables unit33 to be operative for use throughout the structure.

An electrical ON/OFF switch 75 is mounted within or adjacent compartment69 and connected to a source of electrical power by a pair of electricalconductors 77 for controlling a vacuum producing motor 32 such as shownin FIG. 15 or the motor of the central unit 33 as shown in FIG. 7.Switch 75 could be a plunger-type switch that is actuated automaticallyupon insertion of the end of handle 23 into compartment 69 or other typeof switch without affecting the concept of the present invention.Likewise, sealing plate 68 can have other configuration than the springbiased seal as shown in the drawings and described above.

In accordance with another feature of the present invention discussedabove is the attachment of a power driven rotary brush cleaningattachment 26 (FIG. 17) on the end of handle 23 by a wand 28 andconnected to a remote source of high voltage electric power such as120V/240V, by electrical conductors 73 which extend throughout theinterior of cleaning hose 15. An ON/OFF switch 80 mounted on the wand 28is used to control the operation of cleaning attachment 26. The cleaningattachment can be easily removed from the wand 28 by a connection clip78 of the type well-known in the cleaning appliance industry. Thecleaning wand 28 can then be easily detached from handle 23 after thecleaning operation has been completed.

In operation, housing 2 preferably is mounted within various types of anouter larger storage cabinet 5 or could be located in a closet orsimilar area and connected to a vacuum source, either an adjacentself-contained vacuum unit contains motor 32 (FIG. 15) or a remotecentral vacuum cleaning unit 33 (FIG. 7), Housing 2 can be placedvertically as shown in the drawings or horizontally without affectingits operation. The cleaning hose is operational immediately uponremoving handle 23 from the cradle by automatically actuating switch 53(FIG. 4) upon its upward pivotal movement or by actuating switch 75(FIG. 14). Either type of vacuum unit will automatically turn onenabling the user to easily pull outwardly on the handle hose which willextend the hose from its collapsed position as shown in FIGS. 6 and 8 toan extended position as shown in FIGS. 3 and 7 as it unwinds about thespaced rollers 17. The user then pulls the hose to the needed length toreach the cleanup area and perform the desired cleanup. After thecleanup has been completed, the user merely releases the pulling forceon the hose enabling internal spring 21 of hose 15 and the vacuum forceto retract the hose into storage compartment 13 where it continues tocollapse about the spaced rollers 17. As discussed above, the vacuumsource created in the interior of the hose will also exert a retractingforce on the hose, which in combination with the force exerted by spring21, will permit the hose to be easily retracted automatically intostorage compartment 13 about rollers 17. The user then inserts the endof the handle 23 into interior 48 of tube section 47 or into compartment69 where open end 29 is automatically sealed by sealing plate 68, withswitches 53 or 75 automatically being moved to the OFF positionde-energizing self-contained motor 32 or remote vacuum unit 33.

The relatively small compact size of housing 2 and its ability to hold aconsiderable length of hose 15 and its automatic mode of operation willenable the user to easily remove the hose from its position withincradles 49 and 66 for cleaning up small spills or other dirt and debrisin an adjacent area which heretofore required the homeowner to remove alength of hose from a storage area and connect it to an adjacent vacuumoutlet valve. Heretofore, after picking up the dirt the user had toremove the hose from the wall mounted control valve and return it to itsstorage area. The collected dirt is drawn through hose 15 and depositedin a dirt receptacle contained in housing 31 (FIG. 7) or in thecollection receptacle of central unit 33 (FIG. 7). It is also understoodthat housing 2 could easily be mounted freestanding in a work area, forexample, adjacent a power saw for cleaning up sawdust or the like, couldbe located within a cabinet in an RV, boat or other vehicle where spaceis limited. Regardless of its location and mounting arrangement, it isable to store a relatively long length of hose to reach a considerabledistance from the cabinet when in operation.

Storage system 1 enables an occupant to quickly pickup small quantitiesof dirt, spillage etc. by easily removing handle 23 from its storagecradle and directing open end 29 against the area being cleaned.Afterwhich hose 15 retracts automatically into housing 2 upon releasingthe pulling force on the hose.

In accordance with another feature, the total length of the hose for usein a particular size housing 2 can be determined easily by the followingformula L_(TOT) ΣL+½WπD with reference to FIG. 6, wherein L_(TOT) is thetotal length of the hose, Σ L is the sum of the individual horizontallengths between the center lines of the rollers indicated by L₁, L₂etc., wherein W is the number of rollers, and D is the diameter of therollers as shown in FIGS. 6 and 9.

Another embodiment of the hose storage system of the present inventionis indicated generally at 100, and as shown in FIGS. 18-21. Hose storagesystem 100 is similar in most respects to hose storage system 1described above and preferably includes the same housing as in system 1,including cradle 45, ON/OFF switch 53, shutoff valve 67 and sealingplate 68 as that of system 1, and thus is not described in greaterdetail.

The main feature of embodiment 100 is the mounting of a length of rigidtubing indicated generally at 102, within housing interior 3 in aserpentine arrangement. Tubing 102 is fixedly mounted in the housing,and in the preferred embodiment will include five horizontally extendingstraight sections 104 connected by U-shaped bends or corners 106. Tubing102 can be mounted by various types of attachment brackets (not shown)to the interior of the walls of housing 2 and terminates in an open end108 which is adapted to be connected to a vacuum source, such as centralvacuum unit 33 or to an adjacent self-contained vacuum motor 32 as shownin FIG. 15. The opposite open end 110 of tubing 102 communicates withfront wall opening 20 of housing 2. Tubing 102 can be formed of variousmaterials with the preferred type being a rigid ABS plastic tubinghaving a 2 inch outer diameter and a 1 ⅞ inch internal diameter.However, it is readily understood that the number of horizontal sections104 and U-shaped corners 106, as well as the type and size of tubingused, can vary without affecting the concept of the invention.

In further accordance with the invention, an expandable hose 115 isslidably moveably mounted within tubing 102 and is not rigidly attachedat its inner end 112 to a coupler 114 as in system 1. An annular slidingseal 116 is attached to hose end 112 and is in a sliding, sealingengagement with the interior surface of tubing 102 so as to be slidablymoveable therein from a fully retracted collapsed position as shown inFIG. 19 to a fully extended and expanded position as shown in FIG. 21.Seal 116 preferably is formed of a low friction material, such asTeflon®. Hose 115 is similar to hose 15 described above and preferablyincludes an internal helical spring 21, which exerts a biasing force forcollapsing the hose towards its collapsed condition. FIGS. 18 and 19show hose 115 in a fully collapsed retracted position within the storagehousing with handle 23 being seated within pivotally mounted cradle 45which actuates switch 53 and is sealed by sealing plate 68.

Upon an operator removing handle 23 from cradle 45, it will eitherautomatically start the vacuum source being applied to the interior ofthe hose by actuation of switch 53 or by a switch mounted on the handle(not shown). The operator pulls outwardly on the hose in the directionof arrow H (FIG. 20) to expand hose 115, as well as causing sliding seal116 to move within the interior of tubing 102, moving from the positionof FIG. 19 to that of FIG. 20. Upon further force being applied tohandle 23, hose 115 will expand further, as well as sliding seal 116extending further within the interior of tubing 102 to a fully extendedposition as shown in FIG. 21, in which position sliding seal 116 willengage a stop 118 attached to the open end 110 of tubing 102. Thisenables a greater length of hose to store within housing 2 and beavailable to the user than the construction wherein the inner hose endis firmly connected to the vacuum inlet tube, as in the embodimentsshown above in FIGS. 1-17. It also reduces the pulling force required bythe user for extending the hose from within the storage compartment.Again, as in embodiment 1, the vacuum force being applied to theinterior of the hose will apply a retraction force on the hose,especially when the open end of the handle is closed assisting thehelical spring within the hose to pull the hose completely from itsextended position as shown in FIG. 1 to its fully retracted position ofFIG. 19, as well as collapsing the hose from its expanded condition ofFIG. 21 to its collapsed position of FIG. 19.

Embodiment 100 provides a length of tubing which extends in a serpentinefashion within the housing and contains a length of expandable andslidably mounted hose in the tubing which, in combination with thenatural expansion of the hose, provides a considerably greater length ofavailable hose from the storage compartment without increasing thepulling force required to pull the hose from within the housing byproviding the generally air-tight seal between sliding seal 116 and theinterior of the rigid tubing 102. It is readily understood that theinterior of tubing 102 is air-tight and that although there may beslight leakage of air around sliding seal 116, it is minimal so that itdoes not greatly affect the vacuum cleaning source applied to theinterior of the hose by the vacuum cleaning motor. Hose 115 can be ofthe same type as hose 15 described above or could be a neutrally biasedhose or other type of expandable hose which requires the mounting ofsliding seal 116 on one end thereof and the handle 23 on the other endthereof, while providing the advantages of hose storage system 1described above.

A still further embodiment of the present invention is indicatedgenerally at 200, and is shown in FIGS. 22-35. Embodiment 200 includes ahousing 201 having the general parallelepiped configuration as thatdiscussed above for the other embodiments. It includes a pair of sidewalls 205 and 207, front and back walls 209 and 211 and top and bottomwalls 213 and 215 respectively, which form an internal storagecompartment 202 for storing a length of hose 15 on a plurality of guiderollers 17 as discussed above for the embodiment shown in FIGS. 1-17.Embodiment 200 has a number of additional features and modifications toenhance its usefulness and to facilitate the cleaning of a dedicatedarea.

One of the additional features is a U-shaped mounting bracket 204 (FIG.32) which is adapted to be secured to the base of a cabinet, such asbracket 12 in the embodiment shown in FIG. 1. Bracket 204 has agenerally U-shape with a pair of spaced side walls 206 and 208 with anintervening flange wall 217. Side walls 206 and 208 are each formed withan elongated projection 210 and smaller rear projections 212 which aresnap-fitted in corresponding recesses formed in the exterior surface ofthe spaced side walls 205 and 207 of vacuum storage housing 201. The useof U-shaped bracket 204 enables housing 201 to be easily snap-fittedinto and removed from a storage cabinet 5 without requiring theloosening and/or removal of threaded fasteners or other types ofattachment devices. Bracket 204 preferably is formed of a plastic ormetal sufficiently flexible to enable the projections to be snap-fittedinto the housing recesses.

In accordance with still another feature of embodiment 200, a one-waylatch indicated generally at 216, is pivotally mounted on front wall 209of housing 201 (FIGS. 26 and 27). Latch 216 preferably is formed as astiff metal wire having a curved central section 218 and two free ends220 which project into two openings formed in the housing adjacent sidewalls 205 and 207 to pivotally mount latch 216 thereon. Curved centralsection 218, when in a latched position with hose 15 as shown in FIG.27, extends into one of the grooves or valleys 222 formed in hose 15 byinternal helical spring 21 as shown in FIGS. 12 and 13. To use latch216, a user will merely pivot the latch downwardly to the latchedposition of FIG. 27 wherein curved central section 218 becomes engagedwithin one of the hose grooves 222. This enables a user to merely pullthe hose outwardly from its collapsed position toward the extendedposition which will automatically enable the hose to move past thedownwardly pivoted one-way latch. Upon release of this outward pullingpressure, central section 218 becomes trapped in the most recentlyengaged groove 222 preventing the movement of the hose toward aretracted position. This temporary retention will relieve all retractionpressure on the hose handle caused by the internal spring and vacuumsource avoiding the user to continually apply a puffing force on thehose. Manual pivotal movement of latch 216 from its engaged latchedposition of FIG. 27 to its disengaged unlatched position of FIG. 26 willthen enable the hose to be retracted into the storage compartment in oneof the various manners discussed above. Latch 216 will not restrict thecontinued outward extension of hose 15 but only prevents movement in theretraction direction.

Thus, one-way latch 216 provides an extremely simple, inexpensive andeasily used device for maintaining the hose in an extended positioneliminating retraction force on the hose handle until retraction of thehose into the storage compartment is desired requiring only the simplemanual pivotal movement of the one-way latch to the position of FIG. 26.Latch 216 can also be formed of a rigid plastic or have otherconfigurations so long as it provides a portion which engages grooves222 of the hose automatically as the hose is being pulled outwardly fromthe storage compartment yet which engagement within a selected groovewill prevent retraction of the hose into the storage compartment untilthe latching component is moved out of engagement to an inactive storedposition as shown in FIG. 26.

Still another feature of embodiment 200 is the use of one or moretool-holding brackets 224 and 226 secured preferably on top wall 213 ofhousing 201 (FIG. 23). Tool-holding brackets 224 and 226 may be formedof a simple strip of metal or plastic preferably having an upturned end232 for supporting a tool or cleaning attachment component 234 (FIG.24). A ring 236 may also be provided on one of the tool-holding bracketsfor holding a cleaning brush 238. Brackets 224 and 226 preferably areattached to top wall 213 by thumb bolts 239 which are threadablyreceived within threaded holes (not shown) formed in the housing topwall. Tool-holding brackets 224 and 226 may be formed of metal, plasticor similar materials and have various shapes and sizes depending uponthe particular configuration of the cleaning attachment or tool to besupported thereon.

Another feature of embodiment 200 is the formation of shallow recesses240 (FIG. 34) in housing side walls 206 and 208, which recesses define amajority of the area of the side walls. A complementary-shaped side wallpanel 242 is mounted in each of the recesses 240 and preferably containsprinted indicia of a decorative or instructional nature as to the useand operation of the vacuum storage system. Panels 242 are securedwithin recesses 240 preferably by snap-fit connections (not shown) orother type of easily releasable connection. Panels 242 preferably areformed of a thin lightweight plastic and will be installed by thehomeowner or installer after removal of the housing 201 from a shippingbox 244 as discussed further below.

Still another feature of embodiment 200 is the molding of a plurality ofstub shafts 246 (FIGS. 28 and 35) on the interior surface of the opposedside walls 205 and 207 of housing 201. These stub shafts form aplurality of shafts 248 for rotatably supporting guide rollers 17thereon eliminating the need of installing separate shafts therebyreducing production and material costs. Stub shafts 246 are formedintegrally on side walls 205 and 207 and each has a cylindricalconfiguration and are designated as stub shafts 246A and 246B. Stubshaft 246A is formed with a hollow interior 247 and has a small bottomopening 249 through which a threaded bolt 251 extends into threadedengagement with a threaded opening 253 formed through the center of stubshaft 246B (FIG. 35). Stub shafts 246A and 246B are in opposed abuttingrelationship with bolt 251 securing the stub shafts together, as well asassisting and securing housing 201 in an assembled condition. Prior tosecuring the stub shafts together, a usual hose guide roller 17 isrotatably mounted thereon, preferably by a pair of spaced sleevebearings 245.

Another very important addition in embodiment 200 is a vacuum controlsystem having a control valve indicated generally at 250, which ismounted on a modified hose-receiving cradle 252. Cradle 252 is shownparticularly in FIGS. 28, 29, and 30. Cradle 252 includes a tube section254 preferably having a tapered bore 256 for slidably receiving the endof hose handle 23 therein. This tapered bore configuration provides asliding generally air tight seal for receiving the end of handle 23.Tube section 254 is secured to ring 258 which is pivotally mounted by apivot 260 between housing side walls 205 and 207 and extends outwardlythrough an opening 262 formed in housing front wall 209. Ring 258 isformed with a plurality of teeth 264 extending throughout the majorityof its circumference. A boss 266 is formed integrally on an elongatedslide strip 268 which is slidably received within a groove 270 formed intube section 254. Boss 266 is slidably received within a slot 272 formedin a cylindrical collar 274. Collar 274 is telescopically rotatably andslidably mounted on tube section 254 and is provided with a series ofteeth 276 formed about an open rear end thereof. Teeth 276 are adaptedto releasably and selectively engage teeth 264 as discussed furtherbelow.

A stop ring 278 is affixed to a grooved end 280 of tube section 254 tomaintain cylindrical collar 274 on tube section 254. A control knob 282is secured to the outer end of collar 274 and is formed with a throughbore 284 through which the end of hose handle 23 is inserted whenentering tapered bore 256 of tube section 254. Control knob 282preferably is provided with a plurality of axially extending ridges andgrooves 286 for ease of grasping and manipulating knob 282 by a user forcontrolling the vacuum applied to internal hose 15 and subsequently tohandle 23 as discussed further below.

Control knob 282 is movable both in an axial direction as shown by ArrowA and in a rotational direction B (FIG. 31). Pulling outwardly oncontrol knob 282 in the forward direction of Arrow A will slidecylindrical collar 274 including strip 268 and boss 266 along tubesection 254 in groove 270 until stopped by stop ring 278. This outwardaxial movement disengages teeth 264 and 276 enabling knob 282 to berotated in the direction of Arrow B which will change the position ofboss 266 in slot 272. Strip 268 is connected to a control cable 288(FIGS. 28 and 28A) which passes along the interior of the housing andthrough an eyelet 290 until terminating and secured to a connector 292.

Connecter 292 is secured to a collar 294 which is coaxial with andslidably mounted on a short section of tube 296. Tube 296 is the vacuumconnection tube which connects hose 15 to a vacuum source. Tube 296 hasan outer open end 298 which preferably extends outwardly from the rearwall 211 of housing 201 for subsequent connection to a vacuum connectiontube such as tubing 35 as shown in FIG. 7. Tube 296 is secured within anopening (not shown) in the rear wall of housing 201 by a mounting collar300 or other type of connection. Connection tube 296 is formed with aplurality of air exhaust holes 302 and may have a threaded end opening304 for ease of connection to hose 15. A spring 306 extends betweenconnector 292 and collar 300 and biases collar 294 in the direction ofArrow C (FIG. 28A).

The operation of the vacuum control system is shown particularly inFIGS. 28-31. As discussed above, a source of vacuum is connected to tubeend 298 and subsequently to hose 15 through the hose connection tovacuum tube 296 at open end 304. The user wishing to change the strengthof the vacuum source which is subsequently applied to handle 23 of hose15 will pull axially outwardly on control knob 282 which will movecylindrical collar 274 and slide strip 268 and boss 266 axially alongtube section 254 and disengage teeth 276 from teeth 264. Knob 282 isthen rotated which will rotate attached collar 274 resulting in boss 266moving along slot 272 which will subsequently move boss 266 and strip268 in the direction of Arrow D (FIG. 30). Axial movement of strip 268will move attached cable 288 and subsequently attached collar 294 (FIG.28A) along vacuum connection tube 296. Movement of collar 294 willeither cover or expose more holes 302 depending upon its direction ofmovement thereby controlling the strength of the vacuum due to theamount of holes which communicate with the surrounding atmosphere withinstorage compartment 202. Thus, if more holes 302 are exposed upon themovement of collar 294, the vacuum applied to the open end of handle 23will be reduced and vice versa the more holes 302 that are covered bycollar 294 will increase the strength of the vacuum at the open end ofhandle 23.

Thus, a user merely grasps control knob 282 and slides, it slightlyoutwardly and rotates it in either direction for increasing ordecreasing the vacuum force on handle 23 by the movement of boss 266 andstrip 268 and subsequently the sliding movement of control collar 294along tube 296 through cable 288. Upon the inward movement of controlknob 282 and subsequently cylindrical collar 274, the engagement ofteeth 276 with teeth 264 on pivot collar 258 will set the control knobat a desired position. Thus, the vacuum control system enables the userto easily control the strength of the vacuum source by the mere axialmovement and rotation of control knob 282 and once it is adjusted willremain at the desired strength until a readjustment is desired.

A control switch holder 308 is pivotally mounted adjacent to the vacuumcontrol mechanism as shown in FIGS. 28 and 29, for mounting an ON/OFFswitch (not shown) similar to switch 53 discussed above.

Still another feature of embodiment 200 is the formation of a pluralityof holes 312 in each side wall of housing 201 provided by the hollowinteriors 247 and 310 of stub shafts 246A and 246B. Holes 312 are formedeasily in the side walls when molding the stub shafts thereon. Holes 312facilitate the packaging and shipping of housing 201 as shownparticularly in FIGS. 34 and 34A. Each housing 201 preferably iscontained and shipped in a separate shipping box 314. Box 314 will havea usual parallelepiped configuration with spaced end walls 315, sidewalls 317 and a bottom wall 319 forming an internal storage compartment320 preferably closed by four top closure flaps 322. A pair of shippingpanels 316, preferably formed of a corrugated cardboard material as isbox 314, are used for securing housing 201 safely within storagecompartment 320. Each panel 316 has a dimension equal to the insidedimension of box 314.

A plurality of studs 318 (FIGS. 34 and 35) are inserted through aplurality of holes 324 formed in each shipping panel 316 and extend intoside wall holes 312 formed by stub shaft interiors 247 and 310. Housing201 then is placed in the box storage compartment with studs 318extending into holes 312 which are aligned therewith. Next an upperpanel 316 is placed onto the opposite side of housing 201 with studs 318extending through panel holes 324 trapping housing 201 therebetween asshown particularly in FIG. 35. Studs 318 preferably have an annularflange 325 which will place shipping panels 316 in a slightly spacedrelationship shown by spacing 327 from box bottom wall 319 and theadjacent closure flap 322. This provides a slight crush zone between thesides of housing 201 and shipping box 314.

Furthermore, as shown in FIG. 34A, when housing 201 is placed withinshipping box 314 and aligned therein by the insertion of studs 318 inholes 312, a space 329 will be provided between the front and back wallsof housing 201 and side walls 315 of box 314. Furthermore, a spacing 330will be provided between the top of housing 201 and wall 317 of box 314.Preferably, a larger open space 331 is provided between the bottom ofhousing 201 and box side wall 317 than the spacing provided adjacent theother three sides of housing 201 to provide space large enough toaccommodate some floor tools that may be shipped in the shipping box.These spaces provide crush zones providing additional protection tohousing 201 eliminating the need for additional package material and theexpenses associated therewith. This feature again is provided during themolding of guide wheel roller stub shafts 246.

A second shipping panel 316 (not shown in FIGS. 34 and 34A) will beshipped separately in storage compartment 320 of shipping box 314 andwill be snap-fitted into one or both of the shallow recesses 240 priorto installing housing 201 in mounting bracket 204 or other type ofmounting assembly. Preferably, one of the snap-in panels 242 will haveoperating instructions or other indicia printed thereon and this will beplaced in the recess on the exposed side of the housing which is easilyvisualized by inspection of FIG. 1, so as to be readily seen by thehomeowner and user of the improved vacuum hose storage system.

Thus, the third embodiment 200 of the improved hose storage systemprovides a considerable number of additional advantages than the hosestorage system of embodiment 1 and in particular, the vacuum strengthcontrol valve facilitated by control knob 282; the one-way hose latch216 provided by the inexpensive and the pivotally mounted stiff wire;the ease of incorporation of sundry tool holders attached by thumb bolts239 to the housing top wall; the removable side panels 242 which aresnap-fitted into one or more of the pair of recesses 240; the U-shapedmounting bracket 204 which snap-fittedly mounts housing 201 within astorage cabinet; and the molding of the pair of opposed stub shafts forforming hose reel shaft 248 for the rotatable mounting of hose guiderollers 17 thereon.

In the foregoing description, certain terms have been used for brevity,clearness, and understanding. No unnecessary limitations are to beimplied therefrom beyond the requirement of the prior art because suchterms are used for descriptive purposes and are intended to be broadlyconstrued.
